Tripura is one of the seven states in the north eastern part of India
with a geographical area of 10,491 km2. It is located in the south-west
extreme corner of the north-eastern region, between latitudes 22*57' and
24*33' N and longitudes 91*10' and 92*20' E. The state is situated
between the river valley of Myanmar and Bangladesh, and is bounded by
Bangladesh on the north, west, south and southeast in the east it has a
common boundary with Assam and Mizoram.

Tripura
is a land locked state and its geographical limits touch both national
and inter national boundaries. Its length of international boundary line
with Bangladesh measures 839 km. Its national boundaries with Assam and
Mizoram measure 53 km and 109 km respectively.

The terrain by and large consists of parallel hills and ridges running
from the northwest to the southeast direction, with alternating narrow
valleys .

The range of hills rises from the plains of Sylhet in Bangladesh at the
north and proceeds southwards until they join the hills of the
Chittagong hill tracts in Bangladesh. The elevation of hills gradually
increases in the east. The eastern range of the Jampui is situated at an
elevation of 914 meters above MSL and the western range of the Baramura,
Deotamura with its elevation of 244 meters above MSL is the lowest.

Sedimentary rocks which range in age from Miocene to loosely
consolidated sediments of recent age represent the geology of the state.
The rocks are sandstone, siltstone and shale grading into clay. These
rock types are repeated as layers, one above the other. Depending on
their character and the presence of fossils, these sedimentary rock
sequences are divided into Surma group, Tipam group and the Dupitila
group. From the nature of the grains and the texture imprinted on these
rocks, it is inferred that originally the sediments were deposited in
the sea and later converted into rocks. The recent fluvial deposits
occupy quite a large part of south Tripura district. The sedimentary
rocks are deformed and folded.
